High Capacity Magazines

The mags that I bought with my .40 cal P99 are lower capacity mags. Does anyone have a good source for the higher capacity mags? Also, what are your comments on quality for the mags that you have, or have used in the past? Thanks!

As I stated in another post here.
You can buy the SW P99 or SW99 magazines for your pistol. They are the same thing, and will fit in your P99 as exact replacements, they will just say SW on the bottom rather than Walther.
I have looked at the MecGar sight and they do not make magazines for the Walther P99.
Some of the other Walther guns, yes, but not the P99.
